RADIATORuTESTING APPARATUS.

l Application filed April y30, 1921. Serial No. 465,651.

To all whomz'tmay concern: y

Be it known that I, GEORGE S. HALL, a

' @lazen of the United states, residing a Chico, county of Butte, State of California, have invented certain new andusef'ul lmprovements in Radiator-Testing Apparatus; and l do declare the following to be a full, clear, and eXact description 'of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in apparatus for testing automobile radiators for leaks, and is particularly an improvement over that form of apparatus shown in my application for Patent, Serial No. 344,505, filed December 13th, 1919, and allowed January v18th, 1921, the principal object of the present invention being to simplify and render more substantial, the mechanism for raising the table which supports the radiator, so that very little if any wear will be had even after long usage, and the well containing such mechanism may be very easily cleaned out when the occasion arises. A

The above objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification andV claims.

n the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. 1 is a sectional elevation through the tank and well, showing the table raising mechanism.

Fig. 2 is a cross section taken on a line 2 2 of Fig. 1.

Fig. 3 is a top plan view ofthe table.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the tank, of suitable di mensions as to depth, width and length, so as to accommodate, and enable to be completely submerged under the water carried in the tank, a radiator of' any size. Depending downwardly from the tank and preferably positioned centrally thereof is a well 2, closed on the bottom, but open on top and preferably rectangular in cross section, being arranged to receive and form a guide for a rack bar 3 whose teeth 3a mesh with a pinion 4 positioned in a pocket 5 at the upper end of the guide well,`this pocket being integra-l with the well. l The shaft 6 of the pinion is journaled 1n bosses 7 formed with the pocket walls, one boss being lblind-'bored while the other being provided with a form of stuliing'box 60 8 through which the shaft projects. lThe outer end of the shaft is provided with a hand-wheel 9 to turn the same, and also with a ratchet wheel 10 therebehind, the pawl 11 forv said'ratchet being fixed on the V"frame or 65 table 12 on which the tank is supported, The pawl and ratchet are of course positioned to prevent undesired downward movement of the rack-bar.

The lower end of the well is provided with a drain plug 13, and the lower end of the rack with a block of rubber 111 or some similar material, to absorb the shock in the event that the rack should tend to strike the bottom of the well.

On top of' the well is a flange 2a. resting on the bottom of the tank and making a watertight connection therewith.. Seated in the upper end ofthe well is a cover or cap 15 provided with a flange 15a resting on the 80 flange 2a, so that while the cover may be withdrawn from the well by raising it, its weight keeps it vin position and it cannot have lateral movement, even without fastenings.

This cap is provided with an orice 16 through which the rack passes, thereby forming an additional guide for the rack when the latte-r is raised a considerable distance, and also serves to prevent the unavoidable sediment or foreign matter in the water from passing into the well in any appreciable quantity, which would very likely cause a clogging of the gear teeth sooner or later. At the same time it may be easily removed when cleaning is necessary.

The rack 3 supports a table 17 preferably made up of piping and connections to form a cross as at 18, there being a circular band 19 xed to the outer ends of the arms of 100 the cross. A. pin 20 is fixed to the table centrally thereof, and is turnably mounted in the top of the rack.

In operation, the radiator to be tested for leaks is placed on the table, and then submerged under the water in the tank by releasing the pawl which controls the downward movement of the rack. A supply of compressed air is of course operated in connection With the radiator to fill the pas sages of the same, as Was set forth in the application hereinbefore mentioned".

From the foregoing description it will be readily seen that l have produced such a device as substantially fulfills the objects ofl prising4 a tank, a Well depending therefrom,

al bar slidably ymounted in. the Well and provided with means. for supporting a radi-ator, rack teeth o-n the bar,- a pinion meshing with said teethy and journaled in the Well,

a shaft fixed to the pinion and projecting from the Well, and packing means about the shaft Where it emerges from said Well.

2. An apparatus for testingradiatorscomprising a tank, a Well depending therefrom,

Va bar having, a Working it in the Well slidable therein, a rotatable table supported by the bar,.rack teeth on the bar, a pinion meshi ing with said teeth and journaled in the Well kand handvact-uated' means for rotating said pinion from the exterior of the Well.

3. An apparatus for-testing radiators comprisingr' a tank, a. Well depending therefrom,

a: bar iaving'` a WorkingI lit in: the Well slid.- able therein, a rotatable table supported by the bar, rack teeth on the bar, a pinion meshingV with said teeth and journaledy in the Well adjacent the top thereof, a re:- movablecover itted'orver the Well inside the tankandyprovided withy an orice to gni-de the bar, and hand actuated means for rotating' the pinion.

In testimony whereof I affix my signature.
